NEW YORK (Reuters Health) – Chronically itchy skin can take not only a physical toll but a psychological one as well, a new study suggests.
Research has linked various skin conditions, such as severe acne, psoriasis and eczema, to higher risks of depression, anxiety and stress in some individuals. But it has not been clear whether chronic itchiness -- a common symptom of skin disorders -- can cause its own distress.
The new study, of more than 2,200 Japanese adults age 18 and up, found that 3 percent complained of chronically itchy skin, also known as pruritus. And the more severe the problem, the more likely they were to score high on a measure of psychological stress.
The findings suggest that the symptom itself, and not just the disorders it marks, can take an emotional toll, according to the researchers, led by Dr. Yosuke Yamamoto of Kyoto University in Japan.
They report the results in the latest issue of Archives of Dermatology.
The study included 2,224 Japanese adults who kept health diaries over one month and completed a standard questionnaire called the Perceived Stress Scale -- which measures, for instance, how often a person has felt "nervous" or "stressed" in the past month.
Participants used the diaries to record the presence and severity of various symptoms, including itchiness.
Overall, Yamamoto's team found, participants with itchy skin had a higher average score on the stress scale than other participants did. And the more frequent the symptom, the higher the scores.
The link between itchiness and stress was also seen among participants who had more than two health complaints. This, according to the researchers, suggests that itchiness itself has psychological effects independent of other health problems.
A number of skin conditions -- including eczema, recurrent hives and psoriasis -- are marked by sometimes intensely itchy skin. The current findings suggest that if the symptom is not well-controlled, it can be a source of psychological, as well as physical, hardship, according to the researchers.
They point out that the questionnaire they used in the study cannot diagnose clinical depression or other mental health disorders. But people's scores do serve as an indicator of general psychological distress.
In turn, the researchers note, chronic stress may affect the immune, hormonal and cardiovascular systems, potentially affecting long-term physical health.
How Can We Reduce Stress Related To Itchy Skin?Dermatitis-Ltd tells us it is important in the treatment of eczema and psoriasis to treat the cause of the disease and the aggravating factors in as many ways as possible. Those who modify their lifestyles, mind their eating habits, and reduce their level of stress often experience a much greater degree of eczema and psoriasis clearing. There are several excellent methods of stress reduce to aid in eczema and psoriasis control.
Stress is the body's reaction to a perceived threat. Adrenaline and hormones are released, and the nervous system is activated, sharpening our senses, but simultaneously our pulse raises, our muscles tense and our immune system begins to shut down. Those that cannot relieve stress as needed may experience fatigue, upset stomach, and frequent headaches. Adult acne and rosacea are sometimes by-products of stress and/or dehydration.
Avoid stressful situations. Anger, embarrassment and fright may all result in flushing and trigger rosacea symptoms.
You can combat stress by changing your situation, your attitude toward people and things (we can learn to be positive), and taking the personal time out to have fun and friendship. Sleep eight hours or more per night to help alleviate stress. Caffeine, being a stimulant, can make you hyper and cause difficulty in sleeping.
Stimulants such as coffee, tea, cigarettes, and excessive sugar from sweets and soda are vascular dilators and should be avoided. Sodas (soft drinks, pop) containing aspartame and or NutraSweet cause excessive redness in approximately 30% of rosacea sufferers and should be avoided. Anything that affects the entire body, brain, and nervous system to awaken it in the morning or stimulate it during the day can easily stimulate the sebaceous glands to secrete more oil that has to leave the body via the pores. Also, stimulants create stress.
Aerobic exercise is a great way to alkalize your body by replacing carbon dioxide with oxygen. However, any exercise should be moderated to prevent a build-up of
lactic acid,an acidic byproduct of muscle activity. When your muscles begin to "burn," you know that lactic acid is building up. If you exercise regularly, try to break up your sessions for a maximum of thirty minutes at a time and remember to drink more water on days you are exercising. Otherwise, fifteen minutes of aerobic exercise each day would be a good start.
